2017 Calves part 2: Dr Seuss and Christie

A few weeks ago I wrote a blog about Kipling, one of the reindeer born in 2017 (click here to read the first installment). This week I will write about two more reindeer born in that year and given names belonging to the theme famous authors and poets.

Dr Seuss

Dr Seuss was the first calf I ever got to know due to his unmistakable white face passed down from his mother Merida. From a young age he was full of cheek and character and also had a large appetite for food. As a little dumpy chubster he was probably the reindeer I gave the most fuss to during my first winter in the form of food and cuddles, although the latter I enjoyed more than him. Reindeer aren’t ones for being fussed but it was hard to resist for this little man.

Joe (with flowing long locks!) and Dr Seuss.

Being a male, Dr Seuss went through his 1^st and 2^nd year in true teenage fashion, spending most of his time at the farm and tussling the other young bulls his age during the autumn. In the summer months he would be in our hill enclosure fattening up and meeting visitors. He’s always loved his food and will never let an opportunity go a miss if he spots the white handfeed bag.

At 3 years old and fully grown Dr Seuss was trained to become one of our Christmas reindeer and pull the sleigh on events. Being so relaxed and friendly by this point he took to it very well and looked super impressive with his distinctive large, wide antlers. He was so good, he also featured on the Channel 4 programme ‘A Baby Reindeer’s first Christmas’ as one of the stars of the show pulling Santa’s sleigh with a team which included his fellow co-star and reindeer celebrity, Holy Moley. Since then Dr Seuss has featured in a couple of other film or photography events but I don’t believe I am allowed to reveal them just yet. Dr Seuss is one of our friendliest and still most distinctive reindeer, he’s a lovely lad who all herders have taken a strong liking too. From a small round calf he’s now a whopping size with a huge backside that’s important fat reserves for the winter. That’s my excuse for him anyway.

Back on the snowy hills in December 2021, after a weekend away on sleigh-pulling duty!

Christie

From a young age Christie has always been a very pretty reindeer with her white spotted face and legs. Her mother Caddis was a true great of our reindeer herd and it was actually her who caught my attention when I first started getting to know the herd. At the time Caddis was more or less the matriarch of the herd, she was one of the biggest females in both size of body and antlers and for as long as I knew her, always seemed to produce the biggest calf each year. With all her majesty though, she never seemed too pushy with the other reindeer and was very tame. As a young female Christie never left her side until eventually Caddis had another calf, now known as Sherlock, a year later and Christie was naturally pushed away. Unlike her mother, Christie in nature is a lot shyer. As a yearling she spent almost a whole year free- ranging and although I rarely saw her I was always interested to see how she was getting on. Unfortunately Caddis sadly passed away before Christie was 2 years old and as her last female calf, I wanted Christie to one day take after her mother and become as big and strong as she was. As a two year old Christie did spent more time in the enclosure during the winter when I moved to the Reindeer Centre. Like Kipling I would often try to give her a little extra feed and handling to encourage her to be more tame but she’s never quite become completely relaxed around people. I do see her sometimes handfeed from visitors and stand in and amongst groups of people more but not as regularly as our tame or greedier reindeer. I’ve began to enjoy this characteristic about Christie though, I know she’ll never be like her mum was with regards to how she acted around people but with a little encouragement Christie will still accept your presence and a tasty handful of food. This year I was so excited to see Christie become a mum and give birth to her first healthy calf. A surprisingly dark male called Akubra, who we named after our hat themed year. Like Caddis once did, Christie has produced the largest calf of the year and has also grown an incredible set of antlers for a mother. It’s really nice to see that Christie has taken after her mother in this way and has carried on the legacy of family genetics. I still think the best of Christie is yet to come and although she may not be the tamest of reindeer, I’ll keep doing my best give her that extra bit of food during the coming winter months and see if she grows in confidence as time goes on.

Looking fabulous free-ranging in August 2020.

Photo blog: Storm Arwen

At the end of November 2021 the UK was battered by Storm Arwen. It hit us on a very busy weekend with various teams heading off on Christmas tour – Fiona wrote a blog about that which can be found here. We’ve now had many more storms and lots of snowfall this winter, but I thought that I would share some photos of the reindeer and reindeer herders in the snow taken during the first major wintery weekend of the season…

Me (Lotti) and Colin setting off with our team of reindeer to head to Oban Christmas event.

Hook, Clouseau and Druid leading the boys over for their breakfast.

The wonderful Sheena clearing the way up onto Utsi’s bridge to make the walk less treacherous for our visitors!

Ben H was new to reindeer herding in November when he started working with us, however he is no stranger to snow clearing having worked as a lifty on Cairngorm mountain in the past! He certainly knows his way around a shovel and a bucket of grit!

And finally, the wonderfully snowy view from Utsi’s bridge!

Photo blog: Winter free-rangers

In the winter months, all of our adult male reindeer plus some of our cows roam free on the Cromdale mountains. Tilly and the farm crew take care of their day-to-day feeding but occasionally one of us herders from the Glenmore base will pop over to help. Here is a random selection of photos from one of my recent visits:

Elvis – the oldest male reindeer in the herd

Elvis strutting his stuff – September 2017.

Elvis will be 16 this year, born on the 7^th May 2006. His mother was Esme who was a really sweet natured female in our herd, who also lived to a grand age. Although he is a beautiful ‘Christmas reindeer’ Elvis was a real ugly duckling when he was a youngster. He’s now got old man status and is well and truly retired from any duties, but in his prime he has been out and about on our Christmas tour, greeted our many visitors on the mountain annually and won the heart of many through our adoption scheme.

I remember taking Elvis out on tour over a number of years and he was always a great role model to the younger, less experienced reindeer. He has visited Harrods in London, towns as far south as Cornwall and of course done many other events in Scotland, England and Wales. He grew a lovely set of antlers every year and still to this day amazes us with a great set of antler annually, even at his age!

Fiona, Eve, Oryx and Elvis, with Judi Dench!

He comes from quite a small family and there are no longer any breeding females left in his immediate family line. Okapi, his sister is just like her mum and brother by having a sweet nature and of course like most reindeer is very greedy. She spends all her time on Cairngorm, unlike Elvis who spends all of his time at our Glenlivet site either free range on the Cromdale hills over winter or down at our hill farm during the summer months. Okapi has to remain here as quite a few years ago she had an injury which meant she was unable to breed ever again, however, being so tame and friendly she is a great leader of the herd and often when we bring them in from free ranging in the mountains she helps us herders to do this by following very willingly!

Okapi, Elvis’s sister, in November 2018.

Over the past year Elvis has started to look his age… and fairly so! When getting up from lying down he is that little bit stiffer than he would have been a couple of year ago. The stiffness doesn’t last for too long but I’m sure many of you can relate to this when getting out of bed in the morning. We have put him up onto the Cromdale Hills again for the winter season with the rest of the herd and will catch up with them a few times throughout the week for a feed and check over. Elvis, a few times now, hasn’t shown up immediately when the herd call down off the top ridge, however, him and Bovril (another old boy in the herd) eventually come wandering down at their own pace so we’ve learnt to save a bit back now so the other greedy reindeer don’t eat it all!

Elvis free-ranging on the Cromdales – January 2022.

It will be a sad day when we don’t have Elvis around anymore but he has been a great ambassador to the Cairngorm Reindeer Herd and I’ve known him from my late teens and right through my 20’s and 30’s so he will be a reindeer that I will chat about in years to come so his spirit will definitely live on!

Reindeer Herders 2021

Throughout the year The Reindeer Centre has its core staff with a mix of full time and part time Reindeer Herders. Many of you will know us well, so we’ve got – Fiona, Hen, Andi, Lotti, Ben B, Ruth, Olly, Sheena and Lisette. We also have our hill farm contingent consisting of Alan, Tilly, Derek and Colin. We are here all year round seeing the reindeer (and other animals on the farm) through the different seasons, however we cannot manage all the work ourselves… that would be impossible!

Editor’s note (Ruth): not every herder features in the photos, please do not be offended if I’ve missed any of you lovely herders out! Check out this page on the website for more info and photos about who we all are: Who’s who – The Cairngorm Reindeer Herd

A gathering or reindeer herders for the annual calf naming night – September 2021.

Fiona and two of her favourite things – reindeer and skiing!

Andi and Hen (with Witch stealing the limelight!) in January 2022.

Sheena and Lisette after a particularly wonderful Hill Trip, by the size of their smiles!

The multi-talented Olly with Juniper and Scully – December 2021.

Seasonal herder Harry and Ben B doing a spot of harness training – summer 2021.

Lotti, with the famous Holy Moley – January 2021.

So we call upon seasonal staff who dot in and out throughout the year to help out. The parts of the year that can be busy are: February half term, Easter holidays then of course right through the summer with schools breaking up in Scotland first and English schools going back at the beginning of September. Although we aren’t so busy with tourists through September it is the start of our rutting season so we are busy with reindeer management. At this time of year we are carrying a lot of feed up the hill so it’s a reindeer herders work out! We usually have around 4 different groups of reindeer in various enclosures either running with a bull or the herd of Christmas reindeer and females we aren’t breeding from so plenty to keep us on our toes. Its busy through October half term just before we gear up in preparation for Christmas and our own Christmas tour which runs through November and December. We can all breath a big sigh of relief in January when we take a month off and close the doors to the public. We do however keep the office and reindeer management ticking over amongst the core staff.

Seasonal staff that worked throughout these busy periods in 2021 consisted of – Joe, Nell, Harry, Kate, Mel, Izzy, Colin D, Ben H, Dave, Manouk and Leonie. We even roped in ex reindeer herders Jack and Eve for a busy weekend in December… Once a reindeer herder, always a reindeer herder!

Seasonal herder Nell with her favourite reindeer Ryvita – August 2021.

Ben H was new to the team in November 2021 and is helping out this winter. I’m sure we’ll be seeing him again!

If you’ve been up to visit us in 2021 you’ll have no doubt bumped into a few of these herders both core and seasonal along the way. We are very lucky with our team here at the Reindeer Centre. Everyone works well together, is great with the public and of course fab with the reindeer. Every day we are learning more when it comes to reindeer management but we all take it in our stride and everyone mucks in which is the important thing

2017 calves part 1: Kipling

Surprisingly I’ve been involved with working at the Reindeer Centre for over four years now. Time has certainly flown by and I would never have expected to be living at the Centre or even in the Highlands when I first began back in November 2017.

When I joined the team, the calves were already 6 months old and had been named under the theme of famous poets and authors. Back then they were still little fuzz balls on legs with small sticks for antlers and sometimes even then, a little mischievous. I quickly got to know them individually over a couple of weeks and eventually Kipling, Dr Seuss and Christie became my favourite reindeer calves. Over the four years I’ve had great joy watching them grow into the adults and characters that they have become now and I feel privileged to have known them all their lives up to this point.

In this blog I will write a little about Kipling, look out for a future blog about Dr Seuss and Christie.

I can shamelessly say that Kipling is probably my favourite reindeer in the entire herd. Is it bad to have my favourite? Should I treat them all equally? Maybe, but over the years Kipling has been so much fun to work with and get to know. As a calf, I remember her looking slightly different to the others of her year. She was dark in colour but with an almost silvery sheen to her coat. Her mother, Hopscotch, is quite tame and rather greedy and this instantly rubbed off on her daughter. Kipling has certainly always enjoyed her food!

During the first 2 years of her life, I only worked at the Reindeer Centre through the winter time but would still visit at least once during the summer months and I remember seeing her on the free-range as a young female. By the time I would start work in October for the season, Kipling would be in our hill enclosure and it was during this time her obsession with food grew. Handfeed is certainly one of her favourite foods and she would inhale it out of the hands of our visitors before they could even take her picture. She also became extremely tame and friendly during this time and sometimes behaved more like a dog than a reindeer, brushing up against people and didn’t even mind being stroked. Through the coldest winter months when all the reindeer were free-ranging I would always make sure to give her a few extra handfuls of food to keep her happy. Some of the herders were not too pleased to see me do this as over time this has made her quite pushy when it comes to a food bag and has now lost all manners when it comes to waiting to be fed!

Kipling in September 2019, now 2 years old.

Kipling was so tame as a two year old that she even came on Christmas events with us. We visited Milngavie, Keswick, Bedford and Windsor while on tour and she was so ridiculous when on display in the pen, brushing up against the fence to say hello to people and telling off dogs when they came too close.

At 3 years old Kipling became a mother and I was lucky enough to be the first person to see her after giving birth. In classic Kipling style, she was so food orientated that during her first year of being a mother she would pay more attention to what she could eat rather than keep her calf close by. I got to name the calf after the peas, seeds and beans theme that year and landed on the name Pip after my first family pet dog Pippin. Pip herself is more shy in nature than Kipling but has grown in confidence over the last year and is still close to her mother.

Joe, Kipling and new-born calf who was later named Pip – May 2020.

Kipling, her daughter Pip and her littler sister Juniper free-ranging in December 2021. An inseparable trio!

In more recent times Kipling has become a well known regular to visitors on our Hill Trips. She’s usually the first reindeer to come in and hand feed but has sometimes got a little too pushy in her greed and has been known to be a bit too boisterous for some. I feel that after all the extra food and attention I have given to Kipling over the years I have played my part in creating a food monster. But like people can be around their loved one, I look past this and only see the fun, friendly reindeer that I’ve become so fond of.

Photo Blog: December 2021

As Ben and Fiona have explained in previous blogs (click here, and here to read), we had a busy December with events and parades up and down the country, as well as a busy Centre here in Glenmore with fully-booked Hill Trips and Christmas Fun paddock slots! Plus hundreds of adoption packs to make up and post out, alongside all the usual office antics.

For this week’s blog, I’ve collated a series of photographs found on my phone during this particularly busy month to give a brief snapshot of what went on in the life of a reindeer herder. Turns out I don’t take many photographs whilst I’m sat in front of a computer answering emails so the photos are quite biased to all the fun times I’ve had out and about. Thankfully this makes for a much more enjoyable blog… lots of pictures of reindeer!

2nd of December – The unmistakable snozzle of Dr Seuss enjoying the fresh snow. The first half of the month was snowy and cold, great for the reindeer but unfortunately this meant we had to cancel some of our Hill Trips. Thankfully the majority were able to go ahead without complications.

3rd of December – Olly and I spying for the free-rangers in a winter wonderland. We watched the herd coming to our call from a couple of kilometers away! Note: stances might not be entirely natural. Photo by herder Sheena.

4th of December – Lotti and I went away for the weekend with this wonderful team of reindeer (Clouseau, Bond, Holy Moley, Trilby and Akubra) seen here having a snooze at the Langholm event.

5th of December – After a night at our Lockerbie base, we headed to Lancaster. Here’s Holy Moley trying to beat-up her own reflection whilst in the pen, much to the amusement of the crowd.

7th of December – the first day of our shiny new Mountain Equipment jackets here modeled by Joe and Lotti, whilst giving the calves some extra feed. It’s a tough job but somebody has to do it!

7th of December – Witch having a big stretch after a snooze during Storm Barra! The ice cracked on her side as she stood up and moved – very cool!

8th of December – After one weekend looking dramatic in our paddocks for “Christmas Fun” Sherlock decided he’d had enough and cast his antlers! Here’s Ben modeling the impressive head gear. Soon after, Sherlock and the other young bulls were out free-ranging on the Cromdales.

9th of December – Cowboy, now 7 months old, already knows that tasty snacks are kept in white bags! What a cutie.

12th of December – Fiona and I had an event at a farm near Inverness. Good opportunity to write some adoption letters whilst waiting for people to visit the reindeer!

13th of December – Finding some peace and quiet away from the office by feeding the beautiful free-ranging herd! Note the lack of snow, there was a thaw halfway through the month but still chilly with frosts most mornings which means happy reindeer!

19th of December – Feeding the free-ranging herd again, lovely Sambar leading the herd in whilst busily chewing the cud.

20th of December – Tiree the dog having a snooze in the office, it’s all a bit much for her!

23rd of December – Herder Harry re-joined us again for December. Here he is being all cute surrounded by our cute but greedy calves.

24th of December – Another trip up the mountain to feed the free-rangers. Here’s Puzzle looking great!

26th of December – It was very windy and wild Boxing Day so we dropped down in to the woods to find some shelter on our Hill Trips.

31st of December – Some very snoozy reindeer after the last Hill Trip of 2021! What superstars they are.

Utsi Bridge

Constuction ahead! (or a man with an umbrella, as Olly said!)

If you’ve been to visit our reindeer on the hill at Cairngorm, it’s likely that you’ve walked over Utsi Bridge. Named after the charismatic Sami, Mikel Utsi, who was responsible (along with his wife Ethel Lindgren) for reintroducing the reindeer to Scotland, this bridge gives access over the Allt Mor river to the Chalamain Gap, and – more importantly for us – our hill enclosure.

The second incarnation of Utsi Bridge, which we’ve been using for the past 42 years.

The first incarnation was replaced in 1979 by the Edinburgh and Heriot Watt Universities Officer Training Corps, as a summer engineering project, but after 41 years and being crossed by thousands upon thousands of feet (and hooves), it had reached the end of its safe working life and was due to be replaced. However, as it was the only crossing point for some distance, the new bridge would have to be built first, before the old one was removed. Anyone who has been here will also appreciate how difficult the location was for a major build too – there was no chance of getting a digger down into the valley for example – and as it is in a sensitive area other considerations were also necessary. All of the new materials had to be airlifted in, and the old bridge airlifted out, and this had to be done outside of capercaillie breeding season, to prevent disturbance.

Piles of materials for the new bridge after they were dropped off by the helicopter.

Work began in October 2020, and the work crew from ACT Heritage did a fantastic job, working through rain, sleet, hail, high winds and snow. Not to mention the extra complications of an ongoing pandemic! It was also nice that the crew included Ross, the fiancé of ex-herder Ali. They were very good with us, and would always stop work to give us space when we were leading reindeer across the old bridge. Though the orange safety netting was definitely an entertaining obstacle when leading antlered animals! The second national lockdown from Christmas brought work to a halt for a while, but in March a helicopter lifted out the old bridge, and our twin bridges were down to one sturdy, hopefully long-lasting, shiny new bridge.

Slioch keeping an eye on progress as we cross the old bridge. The orange safety fencing was… entertaining… when passing close by with pointy antlers…

The framework for the new bridge complete.

The wintry Cairngorms weather didn’t help matters!

The final wooden structure being built on the metal framework.

Nearly there, just the steps and finishing touches to go.

Not wanting to lose a piece of the Reindeer Company history, Alan drove a tractor and trailer all the way from our hill farm to collect the old dismantled bridge. Apparently the old steel girders were of a quality that is impossible to buy these days! There is a plan to reinstate the old bridge at a suitable location at the farm.

The helicopter at the Sugarbowl after lifting out the old bridge in sections – the giant metal girders are just visible in the background.

The shiny new bridge in use with the last of the old bridge being dismantled.

It has taken the reindeer a bit of time to get used to the new crossing – the steps were perhaps not quite designed for reindeer strides – but once they’ve been over it once or twice they get the hang of it. It’s great having the edging alongside the steps to guide them in the right direction – the old bridge was rather awkward as the steps didn’t have a rail on each side, so calves would sometimes “miss”! And with the new ample width, we’re still debating if we can be bothered carrying one of our Christmas sleighs down the narrow path to get a photo of a full team of reindeer in sleigh on the bridge – it would fit!

Ever changing reindeer – a photo blog

Whilst sorting through the photos on my phone recently, I thought it might be fun to show how the reindeer change in appearance over the summer months so I put together this little blog. This could have turned in to the longest blog ever but I have tried to restrain myself picking just a handful of reindeer; Camembert, Dr Seuss, Kiruna, Sherlock, Gloriana’s calf, and Christie and her calf.

**Camembert 1** – on the 21^st of June (Summer Solstice) Lisette and I walked Camembert and some other cows out on to the free-range for the summer. Here she is growing her antlers, still to moult last year’s winter coat, and determined Lisette still has some food for her!

**Camembert** 2 – This was the next time I saw her, on the 14th of September after my lovely colleagues successfully brought her and a large group of cows back in to the hill enclosure. She’s clearly had a great summer free-ranging, she looks totally fantastic and is still fat as butter.

**Dr Seuss 1** – it’s no secret that I have a wee soft spot for Dr Seuss so my phone is predominantly full of pictures of him! Here he is on the 20th May, he’s just beginning to moult his winter coat from around his eyes, and his lovely antlers and growing well.

**Dr Seuss 2** *– here’s the big boy again* on the 5th of July looking almost ready for summer in his short coat, with a slightly pink nose!

**Dr Seuss 3** – how smart does he look here?! This was the 8th of September. His winter coat is now beginning to grow through around his neck and he’s had a busy summer growing lovely big antlers, and a big tummy after hoovering up all that tasty hand-food!

**Kiruna** 1 – Here’s two year old Kiruna after hearing one of Ben’s jokes. This was on the 8th of July, his antlers are rapidly going and he’s moulted most of last year’s winter coat.

**Kiruna** 2 – Here’s Kiruna stripping the velvet on the 28th August. His paler winter coat is growing through quickly on his neck and flank.

**Kiruna** 3 – What a handsome lad! Here he is leading the herd in for breakfast on the 7th of September.

**Sherlock 1** – Three year old bull Sherlock on the 11th of June, rapidly growing his antlers and just beginning to moult his winter coat from around his eyes and on his nose.

**Sherlock 2** – 1st of August, looking smart in his short, dark summer coat. He’s grown enormous antlers for a three year old!

**Sherlock 3** – 29th of August, just before his velvet started to strip.

**Sherlock** 4 – Just one day later, here he is midway through stripping his velvet on the 30th of August.

**Sherlock 5** – Handsome boy on the 1st of September, with beautiful clean antlers.

**Gloriana’s calf 1** – The palest calf of 2021, this picture was taken on the 20th May, just one day old. What a cutie!

**Gloriana’s calf 2** – What a fantastic job Gloriana has done! This was taken on the 15th of September. After a summer spent free-ranging Gloriana and her daughter are now back in the hill enclosure. She’s already getting used to being around people on our Hill Trips and quickly learning big green bags = food!

**Christie and calf** 1 – Christie in the background with her thick winter coat, you can still make out her freckly nose. Photo taken on the 27th May when her calf was just over three weeks old (born 4th of May).

**Christie’s calf 2** – I was delighted to catch up with Christie and her calf on the free-range on the 15th of August. Christie has done a fabulous job and has produced a nice big strong boy, well done Christie!

**Christie 3** – Looking beautiful on the free-range with her huge calf on the 15th of August.

**Christie 4** – Photo taken on the 15th of September midway through stripping the velvet from her large antlers. Not only has she produced a large calf this summer, she’s also grown big antlers herself and is in excellent condition. Go Christie! Her winter coat has grown in a lot over the last month.

Through the Eyes of a Reindeer

A visitor recently asked me why reindeer have horizontal pupils. The question had me thinking about the importance of vision to reindeer. It is easy to forget that many animals don’t see the world the same way we do, and reindeer eyes are in many ways different from our own.

Reindeer live in arctic and sub arctic regions that experience hugely variable light levels. Above the arctic circle, they’ll experience 24 hour darkness in winter and 24 hour sun in summer, and no matter how dark it is, they still need to be able to find their food and see predators coming. So how do reindeer eyes cope with their environment?

When you look at a reindeer, the most obvious thing about their eyes is that they are placed on the side of their heads. This is common in prey animals, and it gives them a wide field of vision that means they can see danger coming from almost any direction. The placement of their eyes does mean they have a blind spot right in front of their noses, but aside from this it’s very hard to sneak up on a reindeer!

If you look a bit closer, the next thing you might notice – aside from their beautiful eyelashes – is that they have long, horizontal pupils. This adaption helps focus a reindeer’s sense of sight at the ground level and the horizon – where their food and their predator’s are found. These horizontal pupils also help compensate for the placement of their eyes and reduce the size of that blind spot in front of a reindeer, so that they can see forwards – vital for finding an escape route when on the run from a predator.

If you looked deeper into a reindeer’s eyes, you would find even more amazing adaptions. In 2013 scientists discovered that reindeer eyes actually change colour with the seasons! A layer of tissue in the retina changes from a golden colour in summer to a deep blue in winter. This change means that less light is reflected back out of the eye, helping reindeer keep their vision sharp even in the long dark winter months. This is the first time this kind of colour change in a mammalian eye has been found. It is thought the colour change might be caused by increased pressure in the eye in winter. The pupil is permanently dilated in the dark, and this reduces the space in the collagen structure of the retina, which in turn changes the reflectiveness of the retina and shortens the wavelengths of light being reflected.

*Two dissected reindeer eyes, the left taken from a reindeer that died in winter, the right from one that died in summer. Photo by Glen Jeffrey (The Independent)*.

Reindeer vision is made even more interesting by the fact that they can see into the UV range. There are high levels of UV light present in the polar regions of the world due to the reflections from snow and ice. Many lichens – the favoured winter food of reindeer – are very effective at absorbing UV. Wolf fur as well is also shown to absorb UV, so being able to see UV wavelengths helps reindeer pick out both their food and their predators in the snow (see here for a previous blog on UV vision).

Reindeer seem to view the world quite differently to us, and it’s clear their eyes have had to adapt to many challenges. They’ve had to adapt to pick out predators and hard to find food, to cope with extreme seasonal changes in light, and to deal with the large amount of UV present in the arctic. Their eyes are just another example of how well adapted reindeer are for their environments.
